700R4 swap killing me - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So I'm doing a 700R4 swap from a TH350 right now. It's amazing how many cost over-runs there are. I didn't expect to have to buy TWO new custom shafts instead of one. $275 a piece... ouch. (oh, I have a 4x4 k10 with NP205.)

Ok, I do have a question here though, not just here to complain.

Can anyone educate me a little on torque converter lockup? What is it and how do I know of mine is setup for non-electronic TC lockup? I really don't even understand what it actually DOES exactly.

Thanks in advance for posts.
